Bad illustration: Passiflora caerulea flowers

Sorry, but that image of the Passiflora caerulea flowers is a very bad example, because each side has two flowers, plus they're very similar, plus they are spread far apart. I never could see it! I'm guessing many people freeview as I do: let the eyes float and then try to look at one prominent point, which is tough when there are four flowers swimming around. This image would be good as a difficult challenge, like a tongue twister. Lovely image, though-- you could just crop it to one flower.

Stereoscopy is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. This image of two Passiflora caerulea flowers is arranged as a stereo image pair; it can be viewed stereoscopically by using the cross-eyed viewing method (parallel version here).

Celebrity fan

Might it be worth mentioning somewhere that Dr Brian May, the guitarist of Queen, is a collector of stereoscopic images and equipment. He has a website dedicated solely to stereoscopy: https://www.londonstereo.com/ 81.131.173.194 (talk) 13:08, 1 November 2021 (UTC)

History

There seems to be little here about the history of these images (e.g. when stereo photography was first practiced, when its popularity peaked). Is there some other article that would have more of that? If so, it probably should be prominently linked from this one. - Jmabel | Talk 01:19, 26 September 2022 (UTC)

Got my answer, this should probably be incorporated (with some editing). The following is copied from permalink https://en.wikipedia.org/w/index.php?title=Wikipedia:Reference_desk/Science&oldid=1117105826#When_was_stereoscopic_photography_first_practiced%3F:

The first stereoscopic device, invented by Charles Wheatstone in 1838, used drawings; the type developed in 1849 by David Brewster could use paired daguerreotypes, and was popular until the 1930s.[1] The earliest compact stereoscopic camera that I found: Vérascope, was introduced in 1893 by Jules Richard. --136.56.52.157 (talk) 02:10, 17 October 2022 (UTC)

From the book Instruments and the Imagination: "But in 1849, the Scottish natural philosopher and steadfast opponent of the wave theory of light Sir David Brewster came up with a convenient and inexpensive lenticular stereoscope (see fig. 7.3).²¹ George Lowden of Dundee constructed several models based on this design for Brewster. After a disagreement with Lowden—a common event in many of Brewster’s professional relationships—he unsuccessfully searched for another British manufacturer. During the spring of 1850, Brewster took one of Lowden’s models with him to Paris, where he showed the device to the opticians François Soleil and Jules Duboscq. Within a short time, they began producing Brewster’s stereoscope and accompanying stereoscopic daguerreotypes.²²"^[2] The text goes on to describe that the invention caused a sensation at London's Great Exhibition of 1851, whereupon a craze ensued, as evidenced by over-the-top rave reviews ("a divine gift").  --Lambiam 06:07, 17 October 2022 (UTC)

• Looks like much of this is covered in stereoscope, but nothing here to let someone know that. I'll remedy that. - Jmabel | Talk 00:07, 28 October 2022 (UTC)
